In the same manner, when the I.G.B.T. is turned OFF, the flash emission is stopped, and the flash tube Xe is restored to the original condition after passing an ionized condition. At the same time, a discharge loop through the I.G.B.T. of the capacitor 15 and the discharge circuit 16 is cut off, and the capacitor 15 and a trigger capacitor 22 are charged without trouble even though the cathode potential is increased by the ionizing condition of the flash tube Xe. Consequently, the flash emission can be carried out following the high cycle ON operation of the I.G.B.T. with no interruption of flash emission.

Title: Video signal processor
Inventor: TANAKA SEIICHI
IPC: H04N9/64
Filed: 1991-12-10
Abstract: PURPOSE:To obtain the sufficient Y/C separation performance and to improve the noise elimination effect without increasing the memory capacity or generat ing irregularity of colors on the screen. CONSTITUTION:A Y/C separation circuit 12 for still picture separates first luminance and chrominance signal on the still picture and a Y/C separation circuit 3 for moving picture separates second luminance and chrominance signals on the moving picture. When the S/N of an input composite video signal is relatively satisfactory, switches S1 to S4 perform the parallel processing of the Y/C separation processing for moving picture and that for still picture. When the S/N is deteriorated, the second luminance signal and chrominance signal are given to a cyclic noise reduction circuit to eliminate noise. The fourth chrominance signal with noise eliminated is converted into the same phase as the color subcarrier of a third chrominance signal and outputted by a phase shifter 24. The changeover of switches S1 to S4 is performed during the vertical blanking period. Thus, the color irregularity appearance on the screen at the time of changeover can be prevented.

Title: Method for reducing number of matching cycle times for cache matching memory system
Inventor: YOUNG GENE F
IPC: G06F12/08
Filed: 1997-11-27
Abstract: PROBLEM TO BE SOLVED: To improve the use of a memory in a computer system using cache matching with a directory as a base, by allocating common data cache memory line states to the memory lines of respective data cache memories when a system memory line state is in an occupied state. SOLUTION: Two complexes A and B execute communication among processors 101A and 101B, system memories 105A and 105B, a common I/O device, a cache memory and other constitution members. When the lines are allocated to the state cache memory in the occupied state, a write error and a read error generate allocation and allocation generates substitution. When half of the number of errors or below are write cycles, saved substitution invalidity is more, because a read cycle allocates the common input of a cache.
